[mythtvnz] Fresh install 12.04 - tv_grab_nz-py not populating scheduler

[Paulgir]

I installed the latest LTS Mythbuntu and have all my tuners working.
I have 2 remaining problems with the new install.

1. I have a second drive for recordings.It is set up as I did in the past  
and is being seen
and used by mythtv.The drive has some recordings on it from prior to the  
new install.
I believe that when I first installed this drive and copied old recordings  
onto it,there was some scan function that would
populate the database.I seem to recall it was a menu option somewhere on  
the frontend.

2.Mythfilldatabase is not populating the scheduler.
I'm getting  "FillData: xmltv returned error code 2   and   Error in 1:1:  
unexpected end of file
also "No channels are configured to use grabber."  does not seem right.
I'm using the modified version of tv_grab_nz-py
